@hadden89 Ok, thanks for the info. So far it hasn't been a problem for me, everything has worked well. This error just made me wonder has something changed recently and will this cause problems but I guess I can just ignore it.

The stop of support NPAPI plugins was announced for Chromium browsers to the public in 2014 and stopped in September 2015.
New plugins for Chromium should support PPAPI. But some 3rd party programmers did not update their plugins to PPAPI.
